| Abstract: | Abstract]Through analyzing the earthquake-response of a pier＇s pile-structure, this paper clarifies that soil deformation, caused by strong earthquake, has great influence on the structure. This paper emphasizes the necessity of taking soil deformation into consideration in the process of seismic design. In this paper, the pier, which is at a LNG base transport trestle on a harbor, was modeled with nonlinear fiber element. Meanwhile, the paper discusses the importance of investigation on the variablity of axial-force. |
